GRAlN- METER.

SPECIFICATION forming part of Letters Patent No. .241,659, dated May 17,1 881.

Application filed January 90, 1881. (No model.)

To all whom t't may concern:

Be it known that I, JOHN W. HILL, oi" Cincinnati, in the county ofHamilton and State of Ohio, have invented certain new and usefulImprovements in GrainMeters, of which the following is a specification.

My invention is in the nature ot' an improvement upon an automatic grainweigher for which Letters Patent were granted me April 15, 1873, May 18,1880, and May25, 1880, (reissue;) and it consists, first, in connectingthe balancebobs to the scale-beam by means of links or theirequivalents, whereby the motion ol' the bobs is coincident with andcontrolled by the rise and fall of the beam 3 second, in providing uponthe 'mouth of the spout adjust-able stops against which the maincut-oft'closes, whereby the stricture or opening through which the finalquantity of grain fiows nay be adjusted to the grain used in theweigher; and, third, in constructing the weighing bucket or pan of twoseparate receptacles, and providing said hucket with counterbalancedsectors or a sector, and arranging said receptacles, with relation toeach other and to the sector or sectors, in such a manner that the rateof descent of the full reeeptacle while discharging the weighed load ofgrain will be gradually retarded by the change in position ot' thecenters of gravity of the disclarging and empty receptacles.

In the accompanying drawings, Figure lis an elevation of a grain-weighercontaining the improvements herein described. Fig. 2 is a detached View,in elevation, of the balancebob, connecting-link, and sector of thescale-beam. Fig. 3 is a detached View of the mouth of the spout, showingthe Valves or cnt-offs, and the adjustable stops against which the maincutofi' closes, and Fig. 4 is a detached View of the weighing-bucket andcounterbalanced sector. Fig. 5 is a section of the spout and maincutoff.

Similar letters ot' reference indicate similar parts.

A is the frame of an automatic grairweigher containing thebalancing-beam B, balancingweight B suspenders O C, weighing bucket D,and spout G.

c is an arm upon the suspender 0, upon which is pivoted the gravitatinglatch E.

e is a stud or detent secured to the latch E, which engages with thenotch f of the sector F.

The devices c, E, e, F,f, and a for retaining the bucket in position forthe receptio ot' and for causing the automatic discharge ot' the weighedgrain are, with the exception ot' the device F, fully described in myforner patents of April 15,1873, and May25, 1880, referred to.

H H H' 1-1' are the arms by which the cntoft's h and IL' are Suspendedfrom and actuated by the rock-shaft Ic.

K is the balance-bob, of which there are usually two, one upon each sideof the spout G.

L is the link, usually of hardened steel, attaehed to the beam B by thehardened pivot or stud l, and to the short arm ot' the balancebob by thehardened pivot l'.

It will be observed that by means of thelink L and pivots l and Z' theconnection of the bob K with the scale-beam B is positive, and thatthemotion oi' the bob is controlled, in time and quantity, by the motion ofthe bram.

g is the stop, of which there are usually two, one upon each side of thespout Gr, and attached thereto by the screws g', and made adjustable inposition by means of the stop g By sliding the stops in one directionand securing them in position, the stricture G' between the edge of themain valve h and side of the spout Gr is adapted to large grain-as cornand oats-and by sliding the stops in an opposite direction, thestricture is narrowed to adapt it to sma-ll grain-as flaXseed, rye, andclover.

Experience has shown that an uniform slot or stricture, G', throughwhich the final quantity of grain is taken will not answer equally wellwith all grains, and that the stricture must be adapted to thekind ofgrain passed through the machine. In scales or weighers for warehouseswhere all kinds of grain are to be weighed the stops g may be adjustedby tempering-screws with indeXed hand-wheels, which in one positionadjust the slot for wheat, and in another for corn, and in another forflaX- seed, &(3., the essential requisites of the stops being adjustablein position to adapt the Stricture Gr to the various grains used withthe nachine.

The bucket D consists of two receptacles, D' D', each being constructedto contain, as delivered from the spout Gr, a convenient quantity ofgrain-as ten pounds, one bushel, or five bushels. The recepta-cles D' D'are precisely IOO alike in form and dimensions, and are set to receiveand dump grain right and left.

The sector F is provided with a counterbalance, f of such weight as willpractically produce an equilibrium of the sector in any position in thearc which it describes. By reason of the balanced sector, and peculiardisposition of the receptacles D' D', the full or loaded receptacle ofthe bucketdescends quicker upon the lifting of the stud or detent e fromthe notch f, and strikes the stop S with less impact than with theconstruction of bucket shown in my former patents referred to, where theweight of the sector operates to retard the bucket during the first halfof its travel, when the stud c ot' the gravitating-latch E is liftedfrom the notch f, and to accelerate the motion of the bucket during thelast half of its travel, and causes the bucket to strike the stop withconsider-able impact.

There are other practical advantages obtained by the Construction ofbucket herein shown, such as freely discharging the contents of theloaded receptacle by inversion when it strikes the stop S; by bringingthe center ot' gravity of the receivin g receptacle more nearl y underthe mouth of the spout, and by utilizing a larger percentage of the fullsection of the receptacle D' with the weighed load of grain.

I have described my invention as an im provement upon a certaingrain-weigher for which Letters Patent have been granted to me; but itis obvious that the principle of my invention is not limited toautomatic grain-weighers, as it may be applied to machines for theautomatic weighing or measuring of spirits liquids, and many substanceswhich are capable of being spouted.

Having described my invention what I claim sl. In a machine for theautomatic weighing of grain and other substances, the` combination, withthe weighing-beam B, of the balance-bobs K, positively connected to saidbeam, whereby the motion of the bobs is caused to be coincident with andpositively controlled by the rise and fall of the beam, substantially asand for the purpose set forth.

2. In an automatic weighing-machine, the balance-beam B and thebalance-bob K, connected by means of the link L and pivots l Z',substautially as and for the purpose described.

3. In a machine for automatically weighing fiowing substances, thecombination, with the hopper, of the cut-oti' IL, and the adjustablestop g, arranged to limit the motion of the cutoft' to vary the widthot' the stricture or slot G, essentially as set forth.

4. In a machine for thc automatic weighing and dumping of grain andother substances, the combination of the dumping-bracket D, consistingof the two equal connected receptacles, D' 1)', the counterbalancedsector F, having notches f f, and the gravitatin glatch E, having a studor detent, e, to engage with said notches, substantially as and for thepurpose described.

In testimony whereof I have signed my name to the foregoingspecification in the presence of two subscribing witnesses.

JOHN W. HILL.
